Biodegradation of aromatic hydrocarbons by Haloarchaea and their use for the reduction of the chemical oxygen demand of hypersaline petroleum produced water

► Aromatic degrading haloarchaea found in geographically diverse hypersaline environments. ► Haloarchaea degrade naphthalene, anthracene, phenanthrene, pyrene and benzanthracene. ► Haloarchaea reduce the Chemical Oxygen Demand of hypersaline petroleum produced water up to 70%.
